EBRIGATION 1030B,

. Application filed AprihfZS, 1826.- Serial No. 105,270,

My present invention has to do with the dainnnng of irrigation ditches;and it contemplates the" provision of a peculiar and advantageousirrigation door, susceptible of.

being readily moved from point to point and adapted to be expeditiouslyand. easily placed in position to danra ditclf and being'llsoadapted tobe quiclily'anrl easily renioved for transfer to and use at anotherpoint in the ditch the door being adapted to effectively dam the ditchand to resist the pres sure of Water therein.

To the attainment of the foregoing, the invention consists in theimprovement as hereinafter described and definitely claimed;

In the accompanying drawings, forming part of this specification Fl are4 is a, top plan view of the irrigation ooor per se.

Similar numerals of reference designate corresponding parts in all ofthe views of the drawings. Y

I show in Figures 1 and'2 anirrigation .ditch 1, and it will beunderstood from the foregoing that the function of my novel irrigation,door is to dam the ditch and prevent the flow of water therethrough.

It'is within the purview of my invention to form my novel door of anymaterial or materials compatible. with its purpose though I prefer tohave the door comprise a body plate 2 of appropriate sheet metal,-

and a reinforcing frame 3 applied and connected at 4 to one side of thebody plate. also prefer to have the side anchors 5, ofthe door integralwith the said reinforcing frame 3, it being noted in this connectionthat each side anchor is formed by an .extension of the top bar oftheframe 3 and a pointed prong pendent from said extension, the pendentpron being spaced outwardly beyond the side or ges of the body plate250' as to take secure hold in the ground desig nated by 6.

At an intermediate point 121 the height or? the door a reinforcingmember 7 is interposed betweenthe side portions of the temt'orcing frame3, the said reinforcing member 7 beingapertiircd at 8 to snugly receivethe vertical central anchor 9 of the door, the said anchor 9 being ofgeneral spike-form and being pointed at its lower end which is extendedbelow' the body plate, Figures 1 to 3. The anchor 9 is connected at 10to the top bar of the reinforcingframe 3 and also to 5 the bodyplate 2and is provided at its upper end with a flat head 11 upon which anoperators shoe may be disposed for theconvenient downward thrusting ofthe anchor 9 and the door as a whole.

Each of the anchors 5 is provided with a foot piece 12 which is fixed'to and surmounts the same so that each anchor may be de-' pressed, orforced downwardly into .the ground to the extent shown by dotted linesin Figure 2 by pressure applied with the foot of an operator.

At this point Iw'ould have it understood that the vertical centralanchor 9 is also connected to the reinforcing frame 3- and the bodyplate 2 at the point 13, Figures land 2,

It will be apparent from the foregoing that by virtue of theconstruction of my novel irrigation door and the mode adopted forsecuring the said door against casual movement that the door willeffectively resist the passage of water in an irrigating ditch.

In the practical use of my improvement, 2. door is placed. in. anirrigation ditch inthe manner shown in Figure 2 and water is permittedto collect in the ditch atone side of the said door, and the operatorthen takes I another door such-as shown and places the same in the ditchseveralfeet from the firstnamed door, and after the second door isplaced in workingposition, the first named door is raised and water ispermitted to pass slowly at first so as to avoid the impositionofunnecessary pressure aga nstfthe secondnamed door, and so on; and in'this latter connection it will be appreciated that the fiat headwll ofthe vertical 'central anchor 9 and the plates 12 above the side anchorsrender it feasible for an operator to quickly and conveniently raisemy'novcl irrigating door to the extent desired. l have explicitlydescribed the construction and relative arrangement of theparts embracedin the present and preferred one bodiriient of my at one invention inorder to impart an exact undersiandingof the Said'enr hodiment in 211iof its details. Ido not desii'e. however, in be undei'tood as; limitingmyself to the precise construction disclosed, my invention being definedby my appended Chaim Within the scope of which modificzv Hons may be adewithout afleoiing my invention 0' involving departure (here from.
